1. The problem statement, all variables and given/known data

The point P (1/2, 0) lies on the graph of the curve of y=sin(2x-1) Find the gradient of the tangent to the curve of P

2. Relevant equations

...I don't know

3. The attempt at a solution

What is the geometrical interpretation of the derivative $$f'(x_o)$$ at the point $$(x_o,f(x_o))$$?
